Setting up a Virtual Network
* Make sure all your network harware works properly (e.g. Ethernet Cards, Network cables etc.)
* Click the NetworkManager Applet in your top panel of GNOME environment.
* Select VPN Connections | Configure VPN
* Choose Wired tab
* Click Add button
* Provide your new connection a name
* Trace the MAC address of your Ethernet Card from the existing connection (e.g. Auto eth0)
* Choose IPv4 Settings tab
* Set the Method as “Manual”
* Under Addresses section, Click add button.
* A new tuple (or record or row) appears.
* Fill the column with appropriate data. (e.g. 192.0.0.1 | 255.255.255.0 | 0.0.0.0)
* The subnet mask address must be given as per your IP address
* Click Apply
* Now back to the Network Connection window
* A new network connection will be displayed
* Close it
* Click NetworkManager Applet in the top panel of the GNOME
* Select your network setup
* Wait for a while
* A new network has been set up
Do the same with different IP address for different computers.
Ensure all the IP address fall in the same network.
192.0.0.1 and 192.0.0.2 falls in same network,
but 192.0.0.1 and 220.127.116.11 is not the same.
Now transferring files between two systems and remote shell login
* Ensure your computer has OpenSSH installed in it.
* Else, please spend some time installing it.
* It can be installed by “sudo apt-get install openssh*”
* After installing SSH, type the command to restart it
* sudo /etc/init.d/ssh restart ( in all computers )
* Now check the ssh by the command “ssh localhost”
* If it works properly, now are ready to transfer and share fun
* Have the file to be transferred in a place (let we take sample.txt)
* We want to transfer the sample.txt to strawberry user at 192.0.0.2
* The command is: scp sample.txt email@example.com:. ( . represents home folder)
* Cool, work is done
